SN74LVC1G123: maximum resistance and capacitance on output pulse duration(tw)

Part Number:SN74LVC1G123

Dear Specialists,

My customer is using SN74LVC123 and has a question.

I would be grateful if you could advise.

---

In order to make the pulse width 1 s, Rext = 1 MΩ and Cext = 1 μF.

However, there are things that do not work properly(1/500).

(1) Is there a problem with the resistance (1MΩ)?
If there is a problem, please tell me the reason and the maximum value(Ω).

(2) Is there a problem with the capacitor value?
If there is a problem, could you please let me know why and the maximum value(μF)?

I appreciate your great help in advance.

Best regards,

Shinichi
